Just because you were invited does not guarantee that you will be accepted.
If you were accepted then the messages go out in waves & there is a bit of a backlog at the moment so you need to be patient.
Support are nothing to do with the preview program & wouldn't know if you have been sent an invite or not.
All you can do is wait,if you get in then you'll receive a message,if you don't get in you will not hear anything.
